SPECIFICATION forming part of Letters Patent No. 392,768, dated November 13, 1888. Application filEd December 16, 1887. Serial No. 258.061. (No model.)

To aZZ 207mm it may concern.-

Be it known that I, Gnonen H. Wanrrnlrr, of Montesano, in the county of Ghehalis and Territory of lVashington, have invented a new and Improved Smoking-Pipe, of which the following is a full, clear, and exact description.

My invention relates to an improvement in smoking-pipes, and has for its object to provide a pipe wherein the nicotine will be extractcd from the smoke before entering the stem and be prevented from penetrating the bowl, and wherein the smoke, upon reaching the mouth-piece, will be cool and pleasant, and dirt or sediment be prevented from settling in the stem, and, further, wherein the bowl will never burn and may be colored quickly and uniformly.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters ofreference indicate corresponding parts in all the figures.

Figure 1 is a central longitudinal section through thcbowl of the pipe. Fig. 2 is a plan view of the same with the cap removed, and Fig. 3 is a bottom plan view of the cap.

In carrying out the invention the bowl A of the pipe, which may be made of any desired shape or material, is provided with a central receptacle, B, for tobacco or other article to be smoked, having no direct communication with the aperture in the stem E.

The receptacle B, which is located centrally within the bowl, while illustrated as an integral portion thereof, may, if desired, be made removable, in which case it is secured to the bottom by a screw-thread,or in any other convenient or approved manner.

An annular chamber, D, is made to intervene the inner walls of the bowl and the outer walls of the tobacco-receptacle, adapted to be ordinarily filled with cotton,cl,or other equivalent loose fabric admitting the passage of smoke, a connection being formed between the receptacle B and the chamber D by producing one or more, preferably four, apertures, d, in the side of the said receptacle leading into the said chamber, as illustrated in Fig. 1.

The integral neck E of the bowl, to which the stem E is attached, is provided with the usual channel, 0, which, however, extends but a short distance inward, being connected with an annular groove, (4, produced in the upper edge of the bowl proper by a tube, F, which tube is integral with said neck and the bowl, having an inlet from the groove of the latter at b, as illustrated in Figs. 1 and 2.

The tobacco-receptacle B extends above the bowl, and is surrounded at that point by a rim or cap, H, which cap is provided with an annular channel, h, in the under face to receive the inner flange, b, formed in the bowl by the groove to, and an exterior thread adapted to engage a similar thread cut in the outer Wall of the groove a. The cap thus screwed upon the bowl or secured thereto in any other approved manner renders the chamber D virtually air-tight. A connection is, however, obtained between the said chamber and the stem of the pipe by cutting transversely in the under side of the cap a recess, is, which recess is adapted to intersect the chamber D and registcr with the inlet b to the tube F. Thus in operation the smoke is drawn through the apertures (3 into the chamber D, through the packing therein, up by means of the recess 7; into the inlet Z), through the tube F into the channel. of the neck E, and from thence through the stem.

The abovedescribed construction is particularly adapted to meerschaum bowls or bowls of other material adapted to be colored, as the heated tobacco,not coming in contact with the bowl,will not and cannot burn the same. The smoke also comes cool to the mouth and free from nicotine, while the smoke passing to the stem in the manner shown prevents the latter from being choked by dust or'other sediments. The bowl is also rendered much stronger by the absence of the usual hole in the bottom connecting with the neck.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described pipe, consisting of the bowl A, provided with the tobacco-rcceptacle B, having apertures d in its sides near the bottom, the annular chamber D, surrounding the sides of the receptacle B, the annular and ICO screw-threaded groove a in the upper edge of a, and the transverse recess in, connecting the the bowl, the tube F on the front of the bowl chamber D with the passage b of the tube F, 10 and leading to the top thereof, the neck E, proas specified.

'vided with the channel e, extending inward a short distance beyond the tube F, and the GEORGE WARTMAN screw-threaded cap H, provided with the an- Witnesses: nular groove h, forming two depending flanges MASON IRWIN,
